Darren Ferguson felt his side managed the game well as they beat Crewe Alexandra.
Rovers initially took the lead through Everton loanee Conor Grant, before James Jones equalised for the visitors.
Two second half goals from John Marquis and Tommy Rowe respectively, secured all three points for the league leaders, but Ferguson knew it would be a hard task to see of the Railwaymen.
“It’s a game that I knew would be difficult,” he
“We managed it well, it was very close in the first half but I think they shaded it, what we managed to do in the second half was keep believing and our quality shone through.
“The belief in the camp is very strong, regardless of how the games go and I think the last three games have been an example of that.”
Grant scored his first goal for the club on his second return to the Keepmoat Stadium, with a neat finish into the bottom left corner of Ben Garratt’s goal.
And Ferguson believes the addition of the 21-year-old will only benefit the side.
“Getting that goal gave him a lot of confidence,” explained Ferguson.
“We needed more assists and goals from that area and he will bring that with his quality, him coming back to the club has lifted us.”
